Absolutely, man.

Oh, boy.

So, excellent question, Alec.

Thank you.

So, when I say that the Earth's magnetic field has remained roughly constant, what I mean is, if you look over longish timescales,

its magnitude is roughly constant.

Of course, it varies.

And it reverses sometimes.

And those reversals of the Earth's magnetic field, so we know reversal meaning the North Pole becomes the South Pole and vise versa.

So those happen.

And there's even interesting stories you can tell about how those reversals of the Earth's magnetic field correlate with many ice ages and things like this.

But the idea is that if you average over these periodic reversals or fluctuations, the amplitude of the field has remained roughly constant.

And the idea is that if there was no induction, if there was no dynamo working,

you and I wouldn't be talking, right?

The magnetic field would have diffused very quickly, right, within 10 to the five years.

The Earth would be left without a magnetic field, and the Earth's magnetic field protected from cosmic radiation, right?

And if you were open to that radiation, well, you wouldn't be here, like I said, nor would I. Yeah, thank you very much.

Yeah, yeah, yeah.
